Questions
How big is the Intro Board v1 PCB?
It measures 75 × 25 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Intro Board v1 use?
67 parts, built around the STM32G441KBT6, BMP390, CP2102N-A02-GQFN20 and SST25VF010A-33-4C-SAE. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Intro Board v1 KiCad files?
From the pc-neal/MoonPCB repository on GitHub, at the commit this page was made from: the board is Intro Board v1/Intro Board v1.kicad_pcb and its schematic Intro Board v1/Intro Board v1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Intro Board v1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask pc-neal before reusing the design.
